Hi!↵
Can i get some help with this problem? https://open.kattis.com/problems/turbo↵
I feel like i need to get elements from a c++ set using their index, which is not possible with a normal set.↵
Is there a better suited data structure?↵
Thanks↵

This might help, i'm reaing now but just by the name of it, it s pretty obvious that it is what i needed
